Classify Object Via Classifier Associations

When building an instance model from a predefined Class model, Enterprise Architect can assist in setting classifiers and role names for objects involved in a relationship. For example, if ClassA has association relationships with ClassB and ClassC , you can create an instance of ClassA (ObjectA), then draw an association to a new unclassified object and have the choice of selecting ClassB or ClassC as the classifiers of the new object.

Access Click on the Classified object on a diagram and:Drag an Association to an existing, unclassified object orUse the Quick Linker arrow to create a Link to an existing or new unclassified object, orRight-click on existing Association | Advanced | Instance Classifier (Ctrl+L)

Choose an Association Connector dialog

Field/Button

Detail

See also

Classifier Name

Displays the name (if defined) of each Association connector issuing from the source object's classifier.

If the connector has no name, the value <anonymous> displays.

Association

Represents the source and target classifier elements in each Association connector issuing from the source object's classifier.

If you select one of these, the target classifier becomes the classifier for the target object element.

Select <none> if you want to create the Association, but not based on the classifier relationships.

<Source Object Name> Role

Identifies any Roles defined in the Association for the source classifier element, according to the source role multiplicity setting; if you select one of these roles, this will become the specific Role for the source object, as shown on the name of the element on the diagram.

If the multiplicity is not set, or the upper bound is * (asterisk), just the role name displays in the list.

<Target Object Name> Role

Identifies any Roles defined in the Association for the target classifier, according to the target role multiplicity setting; if you select one of these roles, it will become the specific Role for the target object as shown on the name of the element in the diagram (and on the Binding page of the Association connector Properties dialog).

If the multiplicity is not set, or the upper bound is * (asterisk), just the role name displays in the list.

OK

Click on the Association and source and target roles, then click on this button to:

•

Create the Association between the two objects based on the relationship between the two classifiers, and

•

Make the target classifier the classifier for the target object

If you selected the <none> entry, a simple Association is created and the target object is unclassified.

Cancel

Cancel the dialog without changing any classifier settings.

Notes

•

When creating a new association or object, the Properties dialog might appear before the Choose an Association Connector dialog. Complete any Properties fields as required, and click on the OK button.
